To LU whom, t 'may concern.-

Beit known that we, HOLMES MARSHALL, residing at New York city, State of New York, and JOSEPH T. UEBBING, residing at Cleveland, Ohio, citizens of the United States, have invented certain ne-w and useful Improvements in Computing-Machines, of which the following is a clear, full, and exact description.

Our invention relates to improvements in IO computing-machines, particularly adding-machines; and our object is to improve and simplify the construction of the same.

\ Our invention will be set forth in the claims.

In the preferred embodiment of our inven- I5 tion shown in the drawings we have illustrated a computing-machine combined with a typewriting machine, and in the drawingsy Figure l is a side elevation, partly in section, showing a type-writer, a portion of the 2O computing-machine,and a portion of the mechanism connecting the keys of the type-writer with the computing-machine keys. Fig. 2 is a plan view of the computing-machine and movable plunger-carriage, one row of the machine being' shown in section substantially on the line m it of Fig. 3 and another row in section substantiallyT on the line y y of Fig. 3. Eig. 3 is a side elevation, partly in section, of the right half of any one indicator mechanism.

3o Fig. 4 is aside elevation of the left half of the same construction. Fig. 5 isasectional view through two of the indicator mechanisms at the line .e of Fig. 4. Fig. 6 is a detail of the locking device. Fig. 7 is a side elevation of the motor-handle and the ratchet-and-pawl mechanism for operating the machine. Fig. 8 isa sectional view of Eig.7, substantially on the line g g, looking' in the direction of the arrow in Fig. 7 and showing part of the train of 4o gears which rotates the shafts of the different indicators. Fig. 9 is a section on the line ct t of Eig. 4, showing the mechanism for one indicator for setting it back to Zero. Fig. l0 is a section on the line of Fig. 4, showing a brake mechanism. Fig. ll isasection through one indicator mechanism on the line 0 c of Fig. 4, showing the relative position of the drivingteeth of that indicator. on the same line, showing the position of the carrying-tooth.7 Fig. 13 is a section on the line l CZ of Fig. 3, showing the nine-toothed or ninth driving-wheel of one indicator. Eig. 14 is a section on the line e e of Eig. 3 to show Fig. 12 is a section' the position of the teeth on the five-toothed or fifth driving-wheel with relation to those on the ninth, and Fig. l5 is a section on the line ff of Fig. 3 to show the relative position of the first or single-toothed driving-wheel.

In the preferred embodiment of our invention shown in the drawings we have illustrated one form of a computing-machine embodying our invention and in Fig. l have shown an ordinary Remington type-writer 'combined therewith; but it will be obvious that while some of the features of our invention relate to a combined type-writing and computing machine most of the features of invention hereinafter claimed relate more particularly to a computing-machine, and it will be obvious that the conuJuting-inachine may be used either in combination with a type-writer or by itself alone.

In the embodiment of our invention shown in the drawings the computing-machine is an adding-machine.

Referring' to Fig. l of the drawings, we have shown at the upper portion thereof a typewriter, which may be of any approved form; but for illustration we have represented it as provided with a frame l, which carries suitable keys 2 8, zsc., which are provided with numbersMas, for example, on the upper row of an ordinary Remington type-writer. These keys are pivoted at 4, and each of them is provided with type 6, moved thereby by any suitable connectionsuch, for instance, as the ordinary type-bars 7 8 and connecting-rods 9 and l0. ll is a suitable bed for the paper to be written upon by the typewriter, which receives the force of the blow of the type, and in the present instance it is an ordinary rotatable platen. l2 is a roller for carrying the inking-ribbon. Suitable connections from each of these type-writer keys to the computing-machine are provided and will be hereinafter described.

Referring to the adding-machine more particularly shown in the remaining figures, 13 to 2l are nine movable indicators, and inthe present embodiment of our invention they are rotatable and carry numbers thereon Ifrom u0 to "9, as partially indicated at I9 in Fig. 3. le prefer to provide a separate frame for each indicator, as shown, for example, at 20' 2l', &c., in Fig. 2. These frames preferably run lengthwise of the machine. Te prefer to provide a motor for operating the machine and which may, if desired` be in the form of a reciprocating' handle 28 (see Fig. 7) and a suitable ratchet-andpawl connection for rotating the train of operating-gears, although we do not wish to be limited to this construction. In the present instance the spring-pressed pawl 29 is carried by the handle and at each reciprocation moves the ratchet-wheel 30 one tooth forward in the direction of the arrow in Fig. 7. This wheel 3() carries a circular beveled rack 31, meshing with the beveled gear-wheel 32, which drives the train of gears shown in Fig. 3. The teeth on said wheel 30 are spaced apart and provided with a smooth surface between each two i adjacent teeth, and the handle is adapted by a full movement in the forward direction to give a relative movement between the pawl and ratchet-wheel. 1n this ease the pawl is carried by the handle a distance at least equal tothe distance between two adjacent teeth, but less than that between alternate teeth. The handle will therefore rotate wheel 30 only one tooth at each reciprocation, and even if the handle is not drawn completely forward it cannot catch on the succeeding tooth until the full intended movement of wheel 30 has been given, for the pawl will slip on the smooth portion of the wheel.

Referring now to Fig. 3, we have provided a connecting mechanism between the indicator 19 and the motor 28, which is adapted to cause the motor to move the indicator different amounts, and this connecting mechanism comprises a movable, preferably a rotatable, device having thereon (at each of several points along the same transversely of its direction of rotation) a number of teeth different from the number of teeth at any other of said points. In the present embodiment this device is made up of a shaft 33, preferably carrying thereon a plurality of wheels 34 to 42. Wheel 42 has a single tooth thereon, as indicated in Fig. 15, and each of the other wheels has in this embodiment an increasing number of teeth up to wheel 34, which has nine teeth. Each of the wheels therefore has a number of teeth upon it different from the number of teeth upon any other wheel. These wheels are in the present embodiment separated somewhat and fixed to shaft 33, and the teeth are arranged so that they stand in rows, the first teeth on all the wheels standing in a line along' the shaft in the same position as the single tooth upon wheel 42. Fig. 13 shows the relative position of the teeth, tooth 45 (see Fig. 15) hiding the first tooth on each of the succeeding wheelssuch, for example, as the tooth 44 upon wheel 35. Similarly tooth 46 of Fig. 13 is in the same row and hides each of the teeth of the succeeding wheels except of wheel 42, which has no seeond tooth. It will therefore be seen that the teeth on these wheels form a plurality of parwheels, as shown at 49.

allel rows, and, as seen in Fig. 3, when proceeding from right to left there are an inci'easing number of teeth, said wheels and shaft 33 therefore compi'ising a rotatable device which at each of the several points at which the wheels are located is provided with a number of teeth dilferent from the number of teeth at any other of said points. 1n the present embodiment this device is rotatable and is driven by the motor, and as the uppermost row of teeth is the longest, the second row shorter, the third row shorter than that, te., it will be observed that these teeth are arranged in parallel rows, with the ends in eehelon; but this eehelon arrangement may not be necessary in all cases. Shaft 33 of each indicator mechanism is in the present embodiment of oui invention given one complete revolution at each forward pull on handle 23.

teferring to Fig. 3, we have provided a toothed device which is adapted to engage this other toothed device at any of the said points where in the present embodiment the different wheels are located, and in the present instance this second toothed device is normally unconnected with the motor, but normally connected with the indicator, and this is the construction we prefer. This second toothed device is adapted to engage the d riving device at any one of the said points and may, if desired, compriseaflanged and toothed wheel 47, which is slidable long'itudinally on the square shaft 48, but incapable of rotation around it. 1t is normally held in the position shown, but may move transversely of itself into engagement with one of the drivinglVe prefer to provide a plurality of wheels similar to wheels 47 49, one for each of the driving-wheels 35 to 42. Each of the driven wheels may be normally held out of operative relation to its correspondingdi'iving\vlieel, as indicated by the position of the wheels 39 and 47, which in the present embodiment normally stand in different planes, whereby they are out of operative relation to each other and are held there by a spring-pressed detent 50. A spring 51 by means of the forked lever 52 tends to move this wheel to the left into position to be engaged by the wheel 39.

ln order to cause a wheel on shaft 48 to be connected with any one of the wheels on shaft 43, which may be desired, we provide a selective mechanism. which preferably comprises a plurality of keys 53 to 61 and means operated thereby and adapted to automatically cause shaft 48, and therefore the indicator, to be connected with shaft 33 at any point where the former would be driven by the number of teeth desired. In the present instance we provide each key with a pivoted springpressed detent 50, which when the key is depressed will release a wheel-49, for examplevand allow it to move into position to be engaged by the driving device at the point where one of the IOO IOS

IIO

driving-wheels-for example, 38-is located, which will therefore upon the operation of the motor cause the wheel 49 and the indicator to be rotated live spaces, as wheel 38 has five teeth-that is, the driving device has tive teeth at that particular point. It will therefore be observed that in the present embodiment there are several driven wheels 47 49, Sac., and the selective mechanism is adapted to automatically cause any one of those driven wheels to operatively connect the driving device and the indicator.

The mechanism for connecting the motor with the indicator may also be considered to consist of two sets of movable toothed members, preferably rotatable wheels, each of the members of one set being capable of moving the indicator and each of the members of the other set being movable by said motor and normally unconnected with vbut adapted to engage and move one of the members of the first set, each of the members of one, preferably the driving set, being adapted to move the indicator a different amount from the amount said indicator is moved by any other member of said set. In the present embodiment of our invention the Wheels 47 49, &c., constitute one set, and the wheels 34 to 42 constitute the other set, and, as we have stated above, we prefer to have the set of differentlytoothed wheels 34 to 42 driven by the motor and to have them drive any one of the wheels of the other set; but this may not be necessary in all cases. It will be obvious that each of the wheels 34 to 42 is in the present embodiment adapted to move the indicator 19 an amount different from the amount said indicator is moved by any other wheel of that set.

The connecting mechanism between the motor and indicator (illustrated in Fig. 3) may be further considered to comprise a plurality of connecting mechanisms which are normally incapable of operating the indicator, each of said connecting mechanisms being adapted to cause said indicator to be operated a different amount when the selective mecl anism is operated. Each of these connecting mechanisms in the present instance comprises two members, preferably two toothed wheels. For example, wheels 38 and 49 constitute one connecting mechanism and wheels 39 and 47 constitute another connecting mechanism, the first being adapted to operate the indicator live spaces and the second four spaces, and it will be obvious that the selective mechanism is adapted to cause any one of these connecting mechanisms to operatively connect the motor and the indicator.

The different wheels 34 to 42 may also be considered to constitute a series of members each of which is adapted to operate the indicator a different amount and adapted to be separately-that is, each independently of the others-connected with the indicator, and if the selective mechanism is considered to also include the set of wheels 47 49, &c., it will be obvious that the selective mechanism is adapted to operatively connect any one of the wheels 34 to 42 with the indicator, so that it may be operated any amount desired.

It will be obvious that in an adding-machine where several indicators are provided each one of which has numbers on it only from 0 to 9 an amount above nine cannot be correctly indicated without adding a figure to the next higher indicator. ln order to carry this additioual'tigure to the next indicator, we have provided carrying means controlled by one indicator mechanism and operating to move the next higher indicator one figure after the lower indicator has been moved or rotated a certain amount, in the present instance after it has moved beyond the point where the figure 9 is visible through the sight-hole 62. (See Figs. 2 and 3.) In the present embodiment, as shown in Fig. 5, we have provided on shaft 48 a wheel 63, which has a single tooth 64, which when the indicator shows the {igure 9 stands in the position shown in Fig. 5; but when the indicator is moved to O7 this tooth raises an arm 65, which is connected to and raises a spring-pressed detent 66 of the next higher indicator mechanism and allows a toothed wheel 67 to move to the left under the iniiuence of spring 68, pressing on the pivoted fork 69, and come into position to be engaged by a wheel 70, provided with a single tooth, which when the latter is rotated will rotate wheel 67, and consequently the shaft of the next higher indicator, asingle space, thus adding or carrying"7 l to the nexthigher indicator. The wheels 67 and 7 0 of that next higher column, therefore, comprise one form of carrying means which is controlled by the next lower indicator mechanism, and they operate to move that highei` indicator one space after the lower indicator has moved a certain amount. In the present embodiment ofour invention the carrying-tooth 77 of the wheel 70 is so positioned that it will move the higher indicator at a time different from the time that indicator is moved by its own connecting mechanism. l e prefer this arrangement, because whcre all the indicators are moved simultaneously it may be desirable to add an amount to a higher column at substantially the same time that an amount is added to the lower column.Y which will cause the indicator of the lower column to be moved beyond the ninth space. l/Ve prefer that the amount to be carried to the higher column shall be carried after the higher indicator has been moved by its own connecting mechanism, and therefore we have positioned this carrying-tooth 77 behind the ninth tooth on the wheel 34, as indicated in Figs. l1 and l2. ln Fig. l2 the relative position of wheel 70 with relation to wheel 34 is shown by comparison with Fig. 13, and in Fig. 1l

two wheels have been indicated together to make this postponed position of tooth 77 additionally clear. Fach of the indicator mechanisms, except of the first or lowest column, is provided with such a carrying-tooth.

In the present embodiment each of the indicators is provided with a construction like that shown in Figs. 3 and 4 and also with a carrying mechanism like wheels 67 and 70, and the shaft 33 of each indicator mechanism is rotated at every reciprocation of the motor-handle. This is accomplished by means of the train of gears shown in Fig. 8, the Wheels 72, 73, 7 4 being idlers and each shaft 33 having on it a wheel 76. XVe prefer this construction in which all of the wheels 34 to 42 are simultaneously rotated at each operation of the motor; but it will be obvious that we do not intend to limit ourselves to this construction.

1t will be obvious that after the motor has been operated and the indicator rotated the connecting' mechanism-for example, wheels 49 and 38should be restored to their normal position-that is, in the present instance, so that they are out of contact with each other. In the present embodiment we have made the `shaft 48 of each indicator mechanism slidable ylongitudinally in rotatable bearings 78. This shaft is normally kept in the position shown in Figs. 3 and 4 by a coiled spring' 79, located between the brake-wheel 80 and a collar 81, fixed to the shaft. Shaft 48 is also provided with a collar 82, fixed to it, and a fork 83, the fingers of which fork are located in the annular recess 84 of the collar. The forks 83 of the different indicator mechanisms are mounted on and fixed to a rocking shaft 85, which passes transversely through the machine and is provided with an upward extension 86, around which is passed a link 87, made of a loop, which is at one end fastened to the handle 28. Vhen the handle is thrown forward, the indicators will be rotated, and after they have been rotated the end 88 of the loop will strike against the head 89 (see Figs. 4 and 7) and throw the forks 88 to the right in Fig. 4, and consequently push the shafts 48 to the right. These shafts carry stops 90, (see Fig. 3,) which the wheels 47 49 strike against, and if any of these wheels are in their set position (shown by the wheel 49) they will be carried to the right until their detents 50 again engage the same, when they will be held in their normal position. This restoring of the connecting mechanisms to their normal position is thus automatically accomplished by a reciprocation of the handle.

Tn order that the operator may restore the connecting mechanisms of all the indicators to their normal position without adding vany amount, we have provided an additional restoring mechanism, consisting` in the present embodiment of an additional fork 91 (see Figs. 2 and 4) and an additional collar 8l for each shaft 48. These forks 91 are fixed to a transverse shaft 92, which (see Fig. 9) is provided with a coiled spring 93, tending' to hold the same in the position shown in Fig. 4. A handle 94 may also be provided by which the operator may at any time throw the handle to the right in Fig. 4 or toward the bottom of the sheet in Fig. 2 and throw all the shafts 48 to the right in Fig. 4 and simultaneously restore al] the connecting mechanisms to their normal position. It will be obvious that this restoring of the connecting mechanisms can be accomplished after the selective mechanism has been operated and before the motor has been operated, and it will be obvious that this mechanism is independent of the motorthat is, the handle 28 does not need to be operated when the handle 94 is operated. The operator can therefore, if he has made a mistake in depressing a key of the machine, restore all the connecting mechanisms of each indicator to their normal position and again strike the keys for the proper amount.

It often happens in operating a computingmachine that the operator will strike proper keys except, perhaps, in one row, and it is therefore desirable to be able to restore the connecting mechanism of that indicator only to its normal positionwthat is, without restoring the connecting mechanism of any other indicator. The projecting or right end of shaft 48 may be provided (see Fig. 3) with a finger-piece 97. The operator may therefore take hold of this finger-piece 97 and pull the shaft 48 to the right and restore its driven wheels to their normal position without interfering with or restoring the driven wheels of any other indicator, and the operator may therefore in this way correct his mistake in the selecting mechanism of that indicator only, if he so desires.

It will be observed that in the present embodiment each indicator is independently rotatable after its selective mechanism has been operated and before the motor is operated, and it is desirable, in order to prevent mistakes, that when the operator restores the connecting mechanism of any one indicator only means should be provided for preventing the accidental rotation of that indicator and consequent indication of an incorrect amount. This we have accomplished in the present embodiment in two wa\,f's, one of which is the finger-piece 97 which is freely rotatable on shaft 48 and which, if the operator inadvertently rotates his hand when operating the restoring mechanism, will itself rotate without turning the indicator. Another device which accomplishes this result and at the same time provides an automatic lock which positively locks the indicator against movement when the restoring mechanism is operated is in the present embodiment a toothed wheel 99, fixed -to shaft 48, and a pin 100, which has, Figs. 4 and 6, a wedge-shaped IOO TIO

end which normally stands in front of the opening between two adjacent teeth on the wheel when the indicator is at rest, but which enters between the teeth whenever the shaft and wheel 99 are moved to the right. This automatically locks the indicator against rotation.

After several amounts have been added on the computing-machine and it is desired to start a new account the indicators should all be set back to zerowthat is, so that zero shall appear through each of the sight-holes. In order to accomplish this result, we have in the present embodiment provided each shaft 48 with a toothed wheel 95, which is longitudinally slidable on, but incapable of rotation around, the shaft and is normally held in the position shown in Fig. 4 b v a light coiled spring 96, which is much weaker than the spring 93.

Referring to Fig. 4, we have provided a connecting mechanism between the indicator 19 and the motor 28, which comprises a toothed driving member, in the present embodiment a toothed wheel 101, fixed to shaft 33, which is driven by the motor. This driving member, as seen in Fig. 9, hasa cut-away portion 102, where teeth have been omitted. A toothed driven member connected with the indicator, in the present embodiment a wheel 95 located on, butincapable of rotation around,

shaft 48, is provided, and which also has a cut-away portion. In the present embodiment, as shaft 33 is given one complete rotation at each forward movement of the handle,

28, the wheel 101 normally stands in the position shown in Fig. 9, and the cut-away portion on that wheel consequently normally stands in a position where it may receive the teeth upon the other wheel 95, as this wheel 95 may be in any position, depending upon the amount of rotation which has been given to the indicator connected with it. This cutaway portion of the wheel 101 therefore allows the two wheels to be moved into operative position with relation to each other without danger of the teeth on one wheel engaging the teeth on the other and preventing such movement. r1`hese two wheels are norlnally out of engagement, and this is preferably accomplished by making' the wheel 95 slidable transversely of itself on the squared shaft 48. A spring 96 normally tends to hold the wheel in the position shown in Fig. 4; but when the handle 94 is thrown to the left in Fig. 4 this wheel is moved to the left to such a position that the teeth on it may enter the cut-away portion on wheel 101, ready to engage the teeth on the driving-wheel 101 when thelatter is rotated. It will be obvious that no matter what position of rotation the wheel 95 is in when such engagement occurs the rotation of the driving-wheel 101 will rotate it until it reaches the position shown in` Fig. 9, when no further rotation will occur, and

consequently the indicator will be set back to Zero, the cut-away portion on wheel 95 then allowing the teeth on driving-wheel 101 to clear the teeth on wheel 95. The cut-away portionvon wheel 95 therefore corresponds to bt ,7 n s L l0 on the indicator-*that 1s, the cut-away portion on it stops its rotation when the indicator has moved to the position where 07 is indicated. IV e prefer to cause the driven wheel 95 to be moved into position to engage the other wheel; but this may not be necessary in all cases. In the present embodiment, as shown in Fig. 2, each indicator is provided with such a set-back mechanism, which are simultaneously operated by the forks 91 on rock-shaft 92 when the handle 94 is thrown to the left in Fig. 4, thus setting all the indicators back to Zero.

In the present embodiment we have provided a very simple frame construction which is of advantage in assembling lthe machines and which also may allow all indicator mechanisms to be made the same, so that they and the frames may be interchangeable in the machine, and if one mechanism becomes damaged it may, with its frame, be removed and another frame and its mechanism inserted in the machine. In the present embodiment we have provided frames, as indicated at 20, 21, dce., on Fig. 2, which are separable from each other and located side by side. Each of these frames, as indicated in Figs. 3 and 4, preferably consists of a base 22, having a top 23, end pieces 24 and 25, and, if desired, suitable stanchions 26 27. It will be observed that each frame carries an operating mechanism for one indicator and also a selective mechanism for that indicator, and any frame may be removed from the machine and replaced by another one without necessitating the dismemberment of the entire mechanism of the computing-machine. Such mechanism carried by each. frame is duplicated in each other frame.

In cases where a ty pe-writer is combined with a computing-machine it is desirable that the type should strike the paper on the type-writer and write the ligure to be added by the indicator mechanism after the mechanism` which causes that ligure to beselected is operated. The operator of a machine will by such a construction be certain that if the type-writer prints upon the paper the ligure to be added he will have operated the proper setting device. In this way he will be certain not to skip or insufiiciently operate the setting device desired. In the present embodiment of our invention (shown in Fig. 3) the computing-machine has several mechanisms, each of which is adapted to cause the indicator to be operated a diiercnt amountfthat is, an amount different from the amount any other mechanism causes the indicator to be operated. In this case one of these mechanisms is, for instance, the wheel 38 and the wheel 49. These IOC IZO

two wheels and detent 50 also constitute a setting' device. fe have also provided a plurality of devices each of y which is adapted to connect one of the type-writer mimeral-keys with a setting device and adapted to operate the same before the type strikes the paper which may be on the platen or bed 11. 1n i the present embodiment one of these connecting devices is the plunger 57 and a connection from the type-writer key, which will operate it. It will be observed that in Fig. 3 the key 57'has been depressed an amount just suilcient to release the wheel L19; but it may be depressed farther, as indicated in dotted lines in Fig. 1, and the connection between the type-writer key 2 and this detent is such that the type 5 will not strike the paper on platen 11 until the detent nieves to the dotted position. (Shown in Fig. 1.) Consequently if the operator sees a figure printed on the paper he will know that he has released the wheel, which will cause the indicator to be operated that amount.

1n the present embodiment we have provided connecting mechanisms between the typewriter key and the keys of the computing-machine, comprising a carriage 103, carrying spring-pressed plungers 10/1 105, &e., which carriage is slidable from left to right over the different rows of keys of the compnting-machinevfor example, on transverse rods 106 and 107-and provided with a suitable escapement mechanism, (indicated generically by 108,) which is operated by the depression of the type-writer key. Each typc-writer key is connected by a link 109 to a lever 110, which operates a bail 111, extending across the machine and adapted to operate one of the plungers, whatever may be the position of the carriage. r1`he general construction described in this paragraph is not claimed by itself alone, and it is therefore not thought necessary to illustrate it any more than has been done. The type-writer keys and their respective bails and levers are held in the raised position by springs 112 or 112.

Referring to Fig. 1, it will bc seen that the type-writer key 2 has depressed its lever 110 and bail 111 and also the plunger 10st just enough 'to release the wheel L19; but its typebar 7 is then in such a position that the type 5 carried by it has not yet struck against the platen, and the key 2 must be depressed slightly farther until the detent is moved to the dotted position, when the type-bar 7 will have been. moved farther toits dotted position and the type will strike against any paper which may be on the platen. Therefore the type will not strike against the paper until after the detent has been released.

rl`he plunger-carriage 103 in the present embodiment normally stands at the left of the machine, and a suitable deviceAsuch, for example,as the strap 113 and spring-drum 11e-may be provided, which, with the escapement 108,

will move the carriage step by step to the right as the n umeral-keys of the type-writer are depressed. ln order to return the carriage to its normal position, in this embodiment at the left of the machine suitable means may be provided for doing so whenever the motor-handle is thrown forward. 1n the present embodiment we have shown a cord 115 passing around pulleys and attached by means of a hook or pin 116, which is adapted to be engaged in any one of anumbcr of holes 117 118 110, (see Fig. 7,) which constitutes one form of an adjustable connection with the motor, by which the carriage may be drawn different amounts to the left, so that it will normally stand over any row of the computing-machine which may be desired. Such a mechanism as generally described in this paragraph is, however, old. lt often happens,however,that an unskilled operator will throw the handle forward too violently, which will give a quick jerk on the cord 115 and throw the carriage to the left farther than is intended. For example, the operator may desire to have the carriage normally stand over the hundreds-column, which in Fig. 2 is the fifth col umn from the right, as the majority of checks or amounts which he is adding may be under one thousand dollars. lf, however, he gives a too violent pull on the handle 28, the carriage may, even though the pin 116 is in the proper hole to cause the carriage to stop over the column desirel, because of the impetus given to it travel up to the thousamls-column or even beyond, and unless the operator notices this he may write his amounts on the type-writer in the proper place on the paper; but every figure which he adds on the machine will be added in a column -higher than it should be. Te have therefore provided a shit'table stop device which is adapted to prevent overtravel of the carriage in its movement in the direction of its normal position, which in the present embodiment is at the left of the machine. 1n the embodiment of our invention illustrated 117 is such a stop device consisting of a collar slidable on the rod 107 and having a projection or handle 118 extending outside of the machine through a slot 119 in the front of the case. This collar 117 has a tight [it upon rod 107, but may be moved by handle 118 to the right or left, as desired. ln Fig. 2 it is shown in a position such that when the carriage strikes against it it will stop over the fifth column from the right thatis, the hundreds-columnwmid will be prevented, even in consequence of a too violent pull on the handle, from traveling beyond the point where it is desired to stop it.

120 is a pointer attached to carriage 103 and also projecting' through slot 110 over the indicators which will show the position of the carriage.

1f desired, a bell, such as 121, may be provided with a clapper which is actuated by the spring-tooth 122, so as to ring the bell when TOO the carriage moves from the fourth columnY to the third column.
